The turmoil in northern Mali is thwarting efforts to treat and prevent obstetric fistula, say health experts and local NGO workers. It is just one example of the fallout from the latest fighting between Tuareg rebels and the Malian army, triggered when rebels began attacking northern military posts in January. Since then, some 195,000 people are estimated to have been displaced by fighting, according to the UN Office for the Coordination of Humanitarian Affairs.
